Engineered to the exact 40x25x20cm personal item limit, this is your guaranteed pass to travel 3 days with zero fees and zero stress.
You're in the boarding line at Gate 7. You’re watching the agent scan bags, feeling the cold rush of anxiety. You hear them announce the flight is full, and you grip your bag, thinking: "Will they charge me $70 to board with this?"
The Problem Wasn't You. It Was Your Equipment. While other bags are just smaller versions of bulky backpacks, The Sizer was engineered around a single job: beating the system. Its "Air-Compliance Chassis" maximizes every cubic centimeter of the 40x25x20cm limit, solving the one friction that lazy design ignores.
Beat the Sizer. Every Time.
Engineered to the exact 40x25x20cm personal item dimensions. This is your guaranteed pass to board Ryanair, EasyJet, and Vueling with absolute confidence.

Pack Like a Pro. Access Everything.
The "Lay-Flat" clamshell opening lets you pack like a suitcase. No more digging. See everything you packed for 3 days in one glance.

The Quarantine Seal.
A separate, ventilated compartment keeps your gym shoes or dirty laundry isolated. It ensures the clean stays clean.

The Floating Tech-Vault.
A padded, suspended sleeve protects your 15" laptop from drops, while dedicated pockets secure your passport, phone, and boarding pass.
Less Friction. More Presence.
This isn't just about saving $70. It’s the silent satisfaction of walking past the sizer without a second glance. It's the agility of deplaning and heading straight for the city while everyone else waits at the carousel. You bought back your time and your peace of mind. That is the Yond Intelligence Status.
The 90-Day "Free Boarding" Guarantee.
Test The Sizer on your next trip. If it doesn't remove the friction from your travel, send it back within 90 days. No friction, no questions asked. If a low-cost carrier (like Ryanair or EasyJet) denies this bag as a free personal item based on its dimensions, we will cover your fee. That is our promise.
